I just need some clarification on the induced EMF Formula.. I know that the negative sign in front of N * dFlux/dt is just an indicator of Lenz's law, but if we were given the magnetic flux as a function of time, would there be situations where -d/dt(F(t)) would be different than just d/dt(F(t))?
Also -- this is a more conceptual question -- when you think about how fields and forces are related in electrostatics, the electric field and mechanical force vectors are parallel. Before learning about the right hand rule, I intuitively thought that magnetic fields would behave in the same manner with regards to the mechanical force, but obviously it doesn't. So my question is, what properties of magnetic fields make it so that the mechanical force is perpendicular to both the field lines and the direction of the moving charge?
One more point that I really need clarification on is the relationship between electricity and magnetism. I produces a B, which produces F. Also changing magnetic flux produces ε which produces I. So basically magnetism is electricity in motion, and electricity is magnetism in motion. However, I do not understand exactly why these concepts hold true - I don't want to simply parrot information -- I'd like to understand and visualize how these concepts work. I'd love a detailed explanation!
Sorry about the long post... these questions have just been bothering me for quite a while now.
